Bugfix: Arrays losing CloudArray interface

[kounelisagis]

This PR fixes the case when tiledb-cloud package is present but instances of Dense and Sparse Array are returned without the correct inheritance from:

TileDB-Py/tiledb/array.py

Lines 425 to 431 in e1f57bd

	return SparseArrayImpl(
	uri, mode, key, timestamp, attr, ctx, preloaded_array=tmp_array
	)
	else:
	return DenseArrayImpl(
	uri, mode, key, timestamp, attr, ctx, preloaded_array=tmp_array
	)

@kounelisagis Thank you! I'd like to see the test at https://github.com/TileDB-Inc/TileDB-Cloud-Py/blob/main/tests/test_threaded_import.py moved to the TileDB-Py project to guard against possible future regressions.

Thanks @kounelisagis ! I ran tiledb-cloud's tests with this branch and the problem is resolved.
